SPRING-WHEEL.

Specification of Letters Patent. Application filed November 26, 1906. Serial No. 345,256;

Patented. March 12, 1907.

To. all whom it may concern: I

Be it known that I, ELON A. NELSON, a citizen of the United States, and a resident of Chicago, county of Cook, State of Illinois, have invented certain new and useful Improve'ments in Spring-Wheels, of which the ollowing is a specification.

This invention relates to sprin -wheels of that type in which the resilience s obtained by means of springs located between the hub and the rim of the wheel; and the object of my invention is to rovide a wheel 0f this character in which t e springs will yield radially and while resisting all other strains tending to displace the hub from its proper position relative to the ring will permit a very slight though almost inappreciable rotary movementof the hub with respect to the wheel to absorb such shocks as are given to,

the driving-wheels of automobiles. I accomplish this by constructin the wheel with a plurality of series of rings ocated between .the rim and the hub, these rings being connectecl together so as to form an almost ri 'dstructureand at the same time to yield un er the undue strains tolwhich said wheels are subjected.

In its preferable embodiment the" wheel com rises a series of seven rings secured to the iiub and to each other,- an outside series of fourteen'rin s connected to each other and to the rim, and a series of seven rings interposed between the rings connected to the hub and the rin s connected to the rim and setimed to bot sets of rings.

'My invention therefore consists in the wheel shown in its preferable embodiment inthe accompanying drawing and which will cation, Figureil -is a side e now be hereinafter more articularly described and then definitely c aimed.

In the drawings accompanying this applievation of a wheel constructed in-a'ccordan'ce with my invention. Fig. 2- is a horizontal section of-part thereof. Fig.- .-3 is a perspective viewof one of the loops for securing the rings together. Fig. 4 is a detail rim separated, s Fig. 5 .is' an ,enlarged detail section view throu h the rim and tire.- Fig. 6'is an enlarge detail perspective of a portion of the 1vlvhleel. Fig. 7 -is a detail. perspective of the u l Referring now to the detailsof the drawings by numerals, the hub of my wheel consists of two side plates 1 and 2, fixedly secured to a central portion 4, the plates 1 and 2 having ears 5, through which are passed bolts, all as clearly seen in Fig. 7. The rimof my wheel is formed of two sections, (designated by the numerals 8 and 10,) these sections being. preferably of endless angle-iron and each section being provided with two sets of lugs or cars 12 and 14, the lugs 12 being on the inside andv the lugs 14 near the outside. The

lugs or ears 12 form means by which the two sections 8 and 1.0 may be bolted or rivetedtogether, as indicated at 16. It will be noticed that the lugs or ears 12 and 14 alternate, so as not to interfere'with each other, and at the sametime permit the'bolts or rivets to ass from the cars 14 on opposite sides of t e rim for the purpose of securing rings between the ears 14, as will be herein-- and these rings snugly fit between the ears 5, forming parts of the hub-plates Land 2, to which they are secured by the bolts 6-. These rings are also secured to each other by special loops 20, which are formed of spring material, so as to slip over the adjoining sec-f tions of the rings, and the ends are'riveted or bolted together, as seen at 21. Around this series of rings is secured a larger series of rings, also seven in number, and each of these rings is secured'to two of the aforesaid rings by means of loops 22, similar to the loops 20 already described... This series of rings, however, is secured only to the smaller rings, and the individual rings of this series 1perspective of parts of the owing the ears or lugs. I

are not secured to each other. v Around this second series of rings and inter osed betweenthem and the rim is a thir series of rings,'this third series comprising large rings, between each two of which is a ring of about the size of'those of the second series. 'The rings of this third set are all secured to each.

other where they touch each other and also to the second series of rings by means of bolts 16. tion to the shape of the'loops which are em- 100 s 24 similar to those before described, l an the outer sides of this series of rings are. i

also secured between the lugs 14 of the'sec tions 8 and. 10 of the rim by means of the I desire to call particular attenployed for the purpose of securing the adja cent sections of the rings together. It will be noted that these loops areof cylindrical shape where they contactwith the fiat sides I of the rings, and this while insuring a proper which is absorbed by the tread portion alone of a pneumatic tire is distributed through a number of rings. As a. matter of fact some resilience is given by practically all the rings within the wheel; but there are at least six rings always in a position to absorb the greatest part of the strain, and since these six or more rings are firmly secured to and reinforced by the other rings a wheel is provided which gives a maximum of rigidity while at the same timepermittirig that re- I silience which 'is so necessary in wheels for use on self-propelled vehicles.

I claim as new is 1. "In a wheel, the combination of a hub and a rim, a s'eriesnf spring-Tings secured to said hub, a series of spring riiigs'secured to said rim, and a series of spring-rings secured to both series ofthe aforesaid rings, substantially as described. I

2. Ina wheel, the combination of a hub and'a'rim, a series of spring-rings secured to said hub, a series of spring-rings secured to said rim, and a series at spring-rings secured to bothseries' ofthe'atoresaid rings, the said rings b'efin'ggradu-ated in size with the smal'lest rings next to the hub and the largest rings-"next to the rim, substantially as described.

3.1 wheel, the combination of a hub and a rim, aser'ies of spring-rings surroundv 'ing said hub and connected thereto and tor.

each, other, a series-of rings within theurimi and connected thereto, and a third-series of,

4., In a wheel, the combination of ahub and a rim, a series of springrings of relativelysmall size surrounding said hub and connected. thereto,- a "series of larger rings around the rings connected with the hub and connected thereto, 'and a series of still larger rings interposed between the second series of rings and the rim and connected both to said rings and to the rim, substantially as described.

5. In a wheel, the combination with a hub.

and a rim-cf a plurality of spring-rings of rings connected to the first setof rings, and a third set of rings connected to the-second set, of rings and to the-rim, this third'set of rings ond sethaving smaller rings inter osed between. them, substantially as descri ed. 6. In a wheel, the combination of a hub, a

rim-formed of two sections having ears or lugs, and spring-rings interposed between relatively small M size surrounding the hub I and connected therewlth, a'-ser1es of larger comprising a set of rings larger than the sec' 4 the hub and the rim, the ears or lugs on the rim forming a means connecting the rings to the rim, substantially as described.

'7. In a wheel, the combination of a hub and a rim, a plurality of series of. springrings located betweenthe hub and the rim,

the said rim being formed in sections eachsection having a flange on its exterior and ears or lugs on the interior, the flanges forming a retaining means for the tire and'the lugs a retaining means for the spring-rings, substantially as described.

8. In a wheel, the combination with a hub and a rim, of a plurality of spring-rings located between the hub and the rim, the said rim being formed in sections and having flanges and two sets of ears .or lugs, the

flanges acting to retain the tire in position, and one set oflugs to'secure the sections of the rims together, and'the other set of lugs to hold the rings in place',';substantially as described.

9] In awheehthe combination with a hub and a rim,of a plurality of series of springrings located between the hub and the rim and loops connecting the rings together,
